Hi guys, i have just bought a 2004 Focus TDCI with 75000 miles on the clock. It has been running fine for the first 50 miles. I put some diesel in it earlier and after about a mile i pulled away from a roundabout and the car had little power and was blowing black smoke out of the back. This lasted about 10 secs then went back to normal. I left it for about an hour and took the car for a drive round the block and it did the same again for a short time then went back to normal. Any suggestions would be greatly appreciated. Many thanks

 

A good thrash is usually a good idea with diesels!!

Give it some redex from a petrol station then open her up on the motor way pal.

 

Fuel filter mate!!!

 

fuel filter dirty fuel m8!

 

could also be an issue with the turbo, worth running a bottle of fuel treatment through it.

 

a split pipe will cause it to be underpowered and blow black smoke out, however it should do that all the time. worth a check though
